New on the Ibuildings techPortal site, there's an article from Rupert Jones that walks you through the installation of Magento Enterprise on a linux-based platform (LAMP).

Magento is an increasingly popular e-commerce platform due to its sheer flexibility, wide range of features and the facility to customise it relatively easily. In this post we will examine how to get Magento Enterprise set up and running. We assume a debian-based LAMP stack but these instructions could be adapted for any other platform as required.

He shows you how to install ionCube first (a requirement for Magento) and how to get the latest Magento package, unpack it and set up some permissions so the application can write to things correctly. From there it's a simple database creation and Apache config away from being setup and working.
